Thermostat Location
Install the thermostat approximately 5 feet (1.5m) above the floor in an area that has a good amount of air circulation and maintains an average room temperature.
Avoid installation in locations where the thermostat can be affected by drafts, dead air spots, hot or cold air ducts, sunlight, appliances, concealed pipes, chimneys and outside walls.

Install the Sub-Base: 

• Remove the sub-base from the body of the thermostat.
• Mount the sub-base as shown below:

INSTALLATION

Provide Power

• Battery Power – Insert the 2 supplied “AA” type alkaline batteries into the battery compartment located in the rear housing of the thermostat. Make sure to position the Positive (+) and Negative (-) sides of the batteries correctly with the +/- symbols in the battery compartment.
• Optional 24 Volt AC power – Connect the common side of the transformer to the C terminal on the thermostat sub-base. In dual transformer installations, the transformer common must come from the cooling transformer.

				COND	Select for condensate overflow monitoring
				DOOR	Select for door open monitoring
				OCC	Select for occupancy monitoring
	[If a Residential profile was selected in setting 1, only the condensate (COND) setting will be available] The dry contact can be used to monitor several conditions. See the table below for an outline of these conditions. WARNING: DRY1, DRY2 terminals are a dry contact relay and should never have voltage applied to them. If not using the dry contact, make sure to select OFF for this setting.

Detailed Description of Dry Contact Settings (Installer Setting 30)
Condensate	COND	This setting is intended for a condensate pan overflow monitor. When the contact is active, the thermostat will immediately disable the cooling compressor(s) and display the message OVERFLOW. After the contact is inactive for 1 minute, the compressor(s) will resume operation and the thermostat display will return to normal.
Door Switch	DOOR	This setting is intended for a door switch monitor. When this mode is selected, the thermostat will only run the occupied (OCC) portion of the program schedule while the contact is inactive (door closed). When the contact becomes active (door open), the thermostat will turn OFF and display the message DOOROPEN until the contact becomes inactive again. There is a 3-minute delay before the thermostat turns OFF. Temperature override is not permitted while the contact is active (door open).
Occupancy	OCC	This setting is intended for the use of an occupancy sensor or mechanical spring-wound timer switch. When active, the thermostat will be forced into the occupied (OCC) portion of the program schedule until the contact becomes inactive. In setting 32 below, the Occupancy Trigger Control can be selected (PROG or UNOC).

No.	Installer Setting	Displayed	Default Setting	Available Settings	Description of Available Settings
31	Dry Contact Relay State	CONTACT	N:0	N:0	Selects a normally open relay
				N:C	Selects a normally closed relay
	[Not available if OFF was selected in setting 30] Select normally open (N:O) or normally closed (N:C) for the dry contact relay terminals (DRY1, DRY2).
32	Occupancy Trigger Control	OCCUPIED	PROG	PROG	Follows current program schedule until the occupied state is triggered
				UNOC	Follows the unoccupied (UNOC) program schedule until the occupied state is triggered
	[Only available if occupancy monitoring (OCC) was selected in setting 30] If the dry contact type was set to occupied (OCC) in setting 30, there will be 2 selections for the occupied state. If PROG is selected (default), the thermostat will follow its normal program schedule until the dry contact is active. When the dry contact is active, the thermostat will only operate the occupied portion of the program schedule and ignore the unoccupied portion of the program schedule. If UNOC is selected, the thermostat will ignore the program schedule and always operate in the unoccupied state. When the dry contact is active, the thermostat will operate in the occupied state for the duration of the contact being active.

33	Compressor Balance Point	BALPOINT COMP	NO	NO	Compressor balance point is disabled
				0 to 50 (-18˚ to 10˚C)	Select a Compressor Balance Point of 0˚ to 50˚ (-18˚ to 10˚C)
	[Only available for 2 or 3 stage heat pump systems with a Braeburn® 5490 outdoor sensor connected] Locks out the use of the heat pump compressor’s heat stage(s) when the outside air temperature is less than the selected setting. During this lockout period, only the auxiliary heat stage will operate.

SYSTEM TESTING

Warning Read Before Testing

• Do not short (or jumper) across terminals on the gas valve or at the heating or cooling system control board to test the thermostat installation. This could damage the thermostat and void the warranty.
• Do not select the COOL mode of operation if the outside temperature is below 50º F (10º C). This could possibly damage the controlled cooling system and may cause personal injury.
• This thermostat includes an automatic compressor protection feature to avoid potential damage to the compressor from short cycling. When testing the system, make sure to take this delay into account.

NOTE: The compressor delay can be bypassed by adjusting Installer Setting 19 – See section 4.
